QUESTION 9 Let y = f(x) = =x3 - 2x2+3x+5. Choose all that applies. A. f(X) has a local maximum at X = 3 B. f(X) has an inflection point at X = 2, i.e. (2,f(2)) is a point of inflection. O C. f(x) increases on the intervals ( - oo , 1) and (3, oo). O D. f(X) has a local minimum at X = 1 QUESTION 10 Use derivative to find the local maximum of the following fu on. V = - 3x2+ 6x + 11 y has a critical point at x = (i.e. input the x coordinate of the critic y has a local maximum of (type an integer or simplified fraction)
